To all whom it may concern: Be it known that'I, WILLIAM an air-brake systembreaks' oif close to the 'ing drawings, 1 indicates angle-cock, which breaking of the train-pipe renders the brake system inoperative.

It very often happens that when a train is in operation the metallic train-pipe breaks at a point adjacent the angle-cock carried by the hose, and when this break takes place it is necessary to take the car on which the broken train-pipe is located into the shops for repair; and it is the object of my invention to provide an emergency-cock that can be readily applied to the train-pipe when such a break takes place, thus maintaining the regular service of the brake mechanism and making a temporary repair that is in every way satisfactory until the car can be taken to the shops where the'broken trainpipe can be renewed.

To the above purposes my invention consists in certain new and novel features of construction and arrangement of parts, in which p 1 Figure 1 is an elevation of a portion of the train-pipe, showing an angle-cock connected thereto, a portion of the hose, and a dotted line m 0c,indicating the point where the break generally occurs the train-pipe. Fig. 2 is aside elevation of my improved emergency angle-cock applied for use.

Fig. 3 is an enlarged detail section taken approximately on the line 3 3 of Fig. 2. Fig. 4 is an enlarged vertical section taken on the line 4 4 of Fi 2. Fig. 5 is a vertical section taken on the inc 5 5 of Fig. 4.

Referring by numerals to the accompanythe usual metallic train-pipe, which is threaded, as indicated by 2, to receive the usual angle-cock 3, that is detachably secured to the hose 4.

The parts just described are of ordinary well-known construction, and, as heretofore stated, the train-pipevery often breaks at Specification of Letters Patent.

My improved emergency an le-cock com,.

one end of which 1s securely held, by meansof a clamp 6, a short piece of hose 7- or-analogous flexible pipe, which is of such a size as that it may be fitted' onto the endof the train-pipe 1 when the sameis cured to the opposite'end of the pi elbow 8, the outer lower end of'whic is interiorly screw-threaded and adapted to receive the screw-threaded nipple 9 thatiscarried bythe end of'thehose 4 and which is normally seated in the angle-cock 3.

The clamp for'securing the flexible hose section7 to the train-pipe 1 comprises a loop 10, with which is formed integral a screwthreaded shank 11. Operating in this loop is a clamping member 12, the forward end of which is bifurcated, as mdioated by 18, and

the end of said member extends downwardly through the lower portion of the loop 10 and its lower end is provided with a slot 14, through which passes a pin 15, the ends stem of the member ,12 is provided on its opposite sides with shoulders 16, and a sleeve 17 is mounted on the shank 11', the upper end of which sleeve bears against these shoulders 16. A combined nut and lever in the form of a straight bar 18 operates on the screwthreaded end .of the shank 11 and when tightened thereon engages'against the lower end of the sleeve 17 and forces the same upwardly on the shank 11. the train-pipe 1, a trainman after detaching the ordinary angle-cock 3 from the nipple 9 carried by the end of the hose 4, screws the free end of the elbow 8 onto said nipple 9, af-
